Notes:
1. Timing measurement reference levels for all speed grades are V OL = 0.8V and V OH = 2.0V. Input AC drive levels are
V IL = 0.45V and V IH = 2.4V.
2. OE/V PP may be delayed up to t CE - t OE after the address is valid without impact on t CE .
3. OE/V PP may be delayed up to t ACC - t OE after the address is valid without impact on t ACC .
4. This parameter is only sampled and is not 100% tested.
5. Output float is defined as the point when data is no longer driven.
